- Joint pain
- Chest Pain
- Visual and Mental Impairment
- Pins and needles
Bad cases may collapse
Build up of nitrogen bubbles in the blood caused by either scuba diving for cabin decompression
Combined weight of atmospheric gases- nitrogen and oxygen creating a downward force.
It varies according tothe height above sea level
- Increased pulse rate
- Unwarrented self confidence
- Lack of concentration
- Heart conditions
- Respiratory illness
- Blood disorders
- Heavy smoking
- Drug and alcohol users
Nitrogen and Oxygen- and a small amount of of other gases
Temperature- approximately 2 degrees per 1000ft.
When air escapes in a rush. Can be heard as an explosive noise, eg: loss of a cargo door.
Total dailure of pressurisation system. Fuselage stays in tact.
Partial failure of pressurisation equipment of slow pressurisation leak. Fuselage will stay in tact and it may go unnoticed until cabin reaches 1400ft and warning goes off.
Conscious- administer while sitting up right
Unconscious- administer whilst in recovering position
Administer oxygen, seek immediate medical assistance and if cleared emergency, inform captain and they will lower aircraft to lower altitude and land ASAP
Hyp- low or reduced
Lack of oxygen
The cabin pressure matches the outside pressure. Warnings will occur when the cabin altitude reaches 14,000ft and above and oxygen is advised.
Sea level to 10,000ft.
- Sucking on a sweet
- Blowing nose
- Holding nose and gently exhaling
- Passing wind/belching
Administering oxygen until condition is relieved.
When gases in your body become trapped and cause pressure due to parts of the body being unable to expand. It can lead to severe pain.
Oxygen, carbon dioxide and rain
Atmospheric pressure decreases. Gas expands at higher altitude, meaning particles are able to spread further apart.
- Air from the engines is pumped through the air conditioning pack and up into the cabin.
- Varying the amount of air allowed to escape through adjustable outflow valves, controls the cabin pressure.
Altitude increasing= breathing deeper and faster
Blueness in fingertips and lips
- A need to breath rapidly
- Discomfort of pain due to pressure of gasses trapped
- Initial effects of hypoxia
Amount of time since sudden lack of oxygen and the start of physical or mental impairment, preventing you from taking rational action. Eg. putting on oxygen mask.
